In AppDynamics, instrumentation refers to how app agents interact with your application software to gather performance data and report it back to the AppDynamics Controller. The first step to instrumenting your application is installing the app agents on the servers where the code runs.

App agents ship with default instrumentation settings that cover the most common types of application frameworks and programming patterns. If your requirements are more complex, you can customize the instrumentation behavior to suit your environment.
